Executing a Server Interchange

Planned server interchanges are initiated on-demand by the reset system

interchange command, or automatically by scheduled daily maintenance. The

latter is administered with the System Parameters Maintenance screen. A

planned interchange normally has no perceivable effect on service. Every active

call, transient call, system link and stimulus, and data transmission is preserved.

The SYSAM-RMT port (also called the Remote Access Port) is dropped,

Prerequisites

Several conditions must be met to guarantee a non-disruptive interchange. If

these are not met, the system will not execute the interchange. All of the following

conditions are expected to be met during normal operation:

The standby server must be fully in service.

That is, handshake is up, shadowing is on, memory is refreshed, and

standby server's state of health (SOH) is "functional". For more

information, see

There can be no minor alarms against the standby's PKT-INT MO.

There can be no ongoing disk operations on either active or standby MSS
